Abstract

A free-piston engine has a stepped piston having a larger end face thereof guided in the compression cylinder, and a smaller end face in the work cylinder. Both the work cylinder and the compression cylinder are connected with a common high-pressure accumulator for initiating the compression stroke or for charging during the expansion stroke.
